Ok got that, actually i had already been down that route, and opened all the relevant html files. All i ever see is the black accordion nav bar.
However when i went to print a copy of the page to show you, the printout shows the page as i would expect (missing some stuff), and while the print dialog box is open the page underneath changes to what i would have expected. Then when the print dialog closes, that page goes back to the black way. I have enclosed 2 files, one the PDF which is NOT what it looks like on screen. The second is a screen snapshot of the same window, which is what is does look like.
If it had been as simple as opening the right file, i would have found that myself LOL 🙂
